Hundreds of miles from home. Stranded in enemy territory. Outnumbered. Short on supplies. It's time to be a hero! When the heroes come across an opportunity to strike against a caravan of Haradrim carrying tributes to the Dark Lord of Mordor, they hesitate only long enough to devise a plan. When the caravan camps inside the walls of a dilapidated desert fortress, the heroes and their allies will launch their ambush. But will their tactics prove sound enough to account for the caravan's greater numbers?

In addition to the new scenario, The Black Serpent, The fourth Adventure Pack in the Haradrim Cycle for The Lord of the Rings: The Card Game, introduces a new Spirit hero, new support for the game's side quests, and a number of player cards that support a variety of traits.
